Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542476, here are decompositions:
- 19 + 31542457 = 31542476
- 37 + 31542439 = 31542476
- 79 + 31542397 = 31542476
- 103 + 31542373 = 31542476
- 313 + 31542163 = 31542476
- 373 + 31542103 = 31542476
- 409 + 31542067 = 31542476
- 439 + 31542037 = 31542476
Showing the first eight; more decompositions exist.
